Navigating government regulations with confidence

Facing the challenge of meeting changing United States’ Environmental Protection Agencies (EPA) regulations for ethylene oxide emissions monitoring can be daunting. However, with the right tools and support, it can become manageable. State-of-the-art solutions can detect the toxic ethylene oxide gas with precision, aiding in compliance navigation, ensuring smooth operations, and protecting workers in their breathing zone.

Meet the challenge with MAX-IR

Ethylene oxide (EtO) is used in applications such as medical equipment sterilization and chemical manufacturing. As a known carcinogen and air pollutant, it is critical to monitor to address both emissions and workplace air monitoring.

The Thermo Scientific MAX-iAQ Ambient Air Monitoring System and EMS-10 Continuous Emissions Monitoring System (CEMS) systems are ideal solutions for monitoring low-level EtO emissions in real time. They provide immediate detection of leaks and exceed US EPA standards with an LOD of 1 parts-per-billion (ppb) with less than 15 seconds responsivities. These robust and reliable systems require minimal downtime and low maintenance, ensuring your operations continue without interruption. Our comprehensive support includes technical expertise for installation, field service, and applications support.

Trust in a solution that safeguards indoor air quality and protects workers from potential exposure to this hazardous gas. With the right system, managing and reducing these risks becomes achievable, ensuring a safe and compliant workplace.

  • Achieve fast, sensitive analysis for immediate detection of leaks
  • Exceed US EPA standards with an LOD of 1 parts-per-billion (ppb) with less than 15 seconds responsivities
  • Depend on robust and reliable operation with minimal downtime and low maintenance
  • Enjoy peace-of-mind with technical expertise including installation, field service, and applications support

Learn how the MAX-iR FTIR gas analyzers, using optically-enhanced FTIR (OE-FTIR) technology, overcome the specific challenges of monitoring EtO trace gases which presents difficulties due to low concentration and high reactivity.

EPA regulations and compliance

Proposed updates

In April 2023, the EPA released the Proposed Interim Decision (PID) and National Emission Standards for Hazardous Air Pollutants (NESHAP) to include more rigorous regulations for monitoring ETO for workplace exposure and stack emissions.

If finalized, these policies will require commercial sterilizers to implement real-time continuous emissions monitoring methods to confirm that the pollution controls are working.

Capitol Building EtO

What is the objective?

The goal is to decrease the release of EtO from these facilities by 80 percent, to levels below the Clean Air Act benchmark for elevated cancer risk, reducing exposure risk to workers and communities, while maintaining critical sterilization capabilities.

What companies will be affected?

The proposed standards will affect the 86 commercial sterilizers operating in the U.S. currently – in addition to any new start-up companies that rely on EtO – by enforcing the installation of new pollution controls and technologies.

Industrial Building EtO

What is the expected impact?

  • Sterilization companies will be required to perform real-time monitoring of EtO that can measure concentrations at or below 10 parts ppb.
  • Data will need to be collected and reported to the EPA twice per year.
  • In facilities with EtO levels surpassing 10 ppb, additional safety measures, such as enforcing personal protective equipment (PPE) use, will be required.

What is the proposed timeline?

The public comment period has closed, and further steps will be required before finalization. Commercial sterilizers will have 18 months to comply with the new requirements once established. It is critical for companies to plan now, so that they are ready to make potential changes.

How can we help facilities in the transition to compliance?

The EMS-10 CEMS and MAX-iAQ instruments, using new OE-FTIR technology, can identify and quantify low-level EtO leaks with a detection limit of 1 ppb, meeting EPA proposed standards.

The systems provide a proven, turnkey solution that combines fast, sensitive, and reliable emissions analysis with the technical expertise needed for smooth installation, calibration, and regulatory support.
